This. Giving Grenadiers a fith man would be the wrong approach because the problems with this faction lie elsewhere. The inability of the MG42 to supress, the sniper beeing knocked out by just looking at it, the lack of proper maps for Ostheer, the overpriced teching along with the usual bad early game for them, ...
I like the 4 man Grenadier squad. It actually feels a bit historically acurate and unique and makes infantry engagements very tactical as you have to care about each member, rather than just moving my blob of 5 model Volks forward. Ostheer is designed as a faction which relies heavily of combined arms and I'd like to keep it that way (in fact more factions should be like that).
I completely agree with that. The Grens are almost the only Unit of the Ostheer that needs nothing and is good as it is!
